True,thats why I would stick with a RINO. It's a lesser of two evils thing. Put the RINO in and when his term is up vote in a real conservative, IF their is one available.
It is exremely hard to replace a RINO with a conservative without first electing a liberal Democrat. If a liberal democrat is going to have to occupy a seat before anyone good can sit in it, that may as well happen now as later.
